LAllIP REFLECTOR.

Application filed August 25, 1922. Serial No. 584,285.

of New York, in the county of New York and State of New York, have invented certain new and useful Improvements jin a Lamp Reflector, of which the followingis' a full, clear, and exact specification.

This invention relates to a class of devices adapted to be used in conjunction with lighting apparatus. 7

My invention has forits object primarily to provide a reflector designed to be employed especially in conjunction with an electrically lighted lamp when supported at a height whereby the rays of light will be radiated in downward directions, in order that the rays which are usually diflused upwardly may be utilized for lightingthe desired area more effectually; lhe; invention consists essentially of an opaque plate with a reflecting surtace on itsunderside, and having a central opening which maybe surrounded by a depending flange with spaced notches in its lower edge. This reflecting plateis adapted to be detachably supported by a cap or other suitable means on the fix- V ture carrying one or more electrically lighted lamps so that the plate'will be positioned in encircling fashion above the lamp, in, order that the reflect ng surface of the platewill radiate downwardly the rays when the lamp is lighted, thereby enabling avoidance of waste of therays of light which are ordinarily directed upward.

A further object of the invention is to provide a lamp reflector of a simple, efficient and durable through one form of reflector embodyin my invention and which shows, the device applied to an electric lamp, and

construction which may be made of appropriate material in any su1t-.

- Fig. 2 isa fragmentary view, showing a V plan, partly in section, taken onthe line The device or lamp l p 10 which may be of any suitable sizeand shape though the form of the plate shown is circular, and the plate maybe made of reflector, has plate polished opaque glassor porcelain or metal n coated with polish .to provide a reflecting surface 11 on its underside. -In the central part of the reflecting plate 10- is an opening, as 12, which may be circularin shape, and

the portion of the plate between this central opening and its outer edge may be concenof spaced notches, as 1 5.

inpractice the reflecting'pl'ate may be detachably mounted by anysuitable means to the fixture, as A, carrying one ormoreelectr1clamps,--as B, though when it is desired to;

inclose the lamp in a translucent globe, as (J, I prefer to employ a form of cap,as '16,

trically curved in a concave-convex shape,

for removably-supporting the globe as well as for removably supporting the reflecting plate 10. 'The cap 16 has a circular top.

plate 17 which may be substantially coneshaped of a maximum diameterslightly less than the'diameter of the opening 12 of the plate 10. On the outer edge of the top plate of the cap 16 is a dependingannular flange 18 which is of a diameter so'that the'annular flange 1 i of the plate 10 snugly fits removinteriorly threaded bosses 19. The number of these'bosses correspond to the number of the notches 15 of the flange 141 of thereflecting plate 10, and the bosses are some-1 what smaller than the notches so that when theflange 14 of the plate lOis positioned accordingly over the flange 18 of the cap the bosses will beseated in the notches for removably holdingthe reflecting plate. on the cap. In each of the-bosses 19 is threaded a thumb screw 20, and these screws are rotatably adjusted interiorly of the cap into engagement with the rim, as D,provided on 1 the edge of theentrance ot the globe C for remova-bly mounting the globe over the lamp and to the device.

In the central art otthc to plate 17 of V the cap 16 is an opening through which the lamp fixture A is removably disposed, and on the edge of this opening of the top plate 'may be an upwardly extending annular flange 21 which may be somewhat larger than the fixture A. 1n part of the flange 21 may be an elongated'opening 21, and serving to detachably fasten the deviceand the ing normally larger than the diameter of the'clectric fixture A, The spring ring 18 arranged within the flange 21 of the cap edgewise so that its spaced ends terminate at -the opening 21 of the flange 21 of the cap, and protruding from the ends of the ring strip are two spaced lugs 24:, 25 which extend through the opening 21 01" the flange 21. The central part of the ring strip is secured, as as 26, to the flange 21 of the cap so that by adjustably moving the lugs 24, 25 toward and from each other the diam eter of the ring strip will be yieldingly varied. In the free end parts of the lugs 24,

25 are registered threaded holes with a screw 2? therein which when rotated accordingly "will cause the Tinstri- 23 to be ex Jansibl r e P l adjusted toallow the ring strip to be passed over the fixture A after removal of thelamp B. By then tightening the screw 27 the ring strip will be clamped to the fixture for removablymounting the reflector thereon so that when the lamp is refl ted in the fixture and the globe C is fastened to the device, as above explained, the reflecting surface 11 of the plate '10 will radiate downwardl the ra sot li ht of the lam-3 which would ordinarily be directed upwardly when the lamp is lighted.

l -n the foregoing descr ption, I have embodied the preferred form of my invention,

but I do not wish to be understood limiti-ng myself thereto, as I am aware that modiflcati ns may be made therein without departingfrom the principle or sacrificing any oftheadyantages of this invention, there- ;tore, l reserve'to myself the right to make such changes as fairly fall within the scope thereof. 2

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A lamp reflector comprising a cap with an apertured top plate having a central opening with an upwardly protruding flange on itsfledge and on its outer edge having an annular depending flange with spaced holes therein provided, with interiorly threaded bosses, a separate plate with a reflecting surface on its under side having a central opening surrounded with a depending'flange in which the flange of the cap removably fits, Said flange of the plate being-provided in its free edge with spaced notches somewhat larger than the bosses of the flange of the 'cap' and adapted to be removably fitted therein-l 2.
